l Specicaton of Letters Patent.

Application led November 15, 1918. VSerial No. 262,634.

Be it Vknown that I, EDWIN I-L-Biinn, a citizen of the 'United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new andV useful Improvements in Adjustable Derailing Devices; and I do 'hereby'declare that the following is a full, clear, and eXactidescription thereo f,reference being had to the accompanying drawingsfand to the letters i of reference marked thereoiigwhich form a part of this specification. A i

^ rlfhis invention relates to improvements in derailing devices and more particularly to y an improvement upon the type of derailing device illustrated, described and claimed in the United States Patent No. 1,109,007, issued to George W. Nibbe, Septemberlst, 1914, wherein is disclosed a derailingdevice adapted to swing about an aXis of rotation, and provided with meansfor vertical adjustment wherebythe derailing device mayV be made to accommodate rails ofl'diderent heights and provided, also, with an operat-V ing link extending transverselyT .under the rail in the usual manner. A

In devices of this type, the derailing block member is'relatively heavy, and when swung about its axis of rotation' under the influence of the operating link, swings a relatively considerable distance away from the rail and through" a considerable Yarc until the rock arm carrying at its outer end the derailing block, is Varrested by the ties on the road bed,-`said rock arm being at that time` in substantially the same horizontal plane as the rail base. Theweight of the rock arm and derailing head proper,` and this swinging movement from the rail, tends somewhat to strain the pivotal connections. Agaim when in this position and it is Vdesired tol swing the derailing head into properposrv tion on' the top of the rail, a very considerable strain has to 4be exerted, inactuating the operating` link in overcoming the dead nient of the derailinghead will be materially decreased, whereby the rock arm and derailing head will'lie 'at an acute angle tothe vertical axis of the. rail when the derailing head isoif the rail, whereby less power is required toactuate the operating link to restore the derailing'head to the railanfl whereby the Vstrain on the connections durl ing -the moving operationrwill be rendered negligible. .l Y

These and other objectsfof the invention are accomplished by providingfmeans on the rocking arm adapted at the extreme point of the movement of the rock arm, to` lie in a plane substantially parallel and in prox` iinitybeneath the rail baseto contact there` with;vthus said arinand rail base form a stop` to :limitthe swing of the rock arni'awav from the rail. A 'u 1 also provide adjustable' means whereby the arresting device may be used in connection with an adjustable derailer.

In the drawings:

Figure lV is a view in sideelevation, of a derailing' device einbodyinglmy invention.

`Fig. 2 is a vertical section through the der ailing device, in a plane indicated by the line 3 3 of Fig. 1. i

Fig. 3 is a similar view showing a modilication. i l I Referring now to that embodiment of my invention illustrated inV the, drawings, vA indicates a rail attached to and supported upon ties 1, inthe usual manner.` The de railing deviceis shown as applied to the rail at apoint between thetwo ties, where a channel. 2 below the raillbase is formed in the ballastor road bed to provide space for the parts of the device'wliich are located below the level of the railbase.

The derailing device includes the usual derailing block 3, which is carried by a rock arm` 4, a supporting Vand attachingmeniber 5 by means of which the device is attached to the railA and by which the rock arm 4 is rotatively carried; and an operating link which extends transversely under the rail `in. the usual manner. The derailing-block 3 forcefthe wheel as it rides upon the block to travel' in afdiagonaldirection across the block from its inner to its outer edge in such manner as to derail the wheel. formation of` said block being of noV particular interesttin the present invention, .further description of the "saine isunnecessary. y

The attaching and supporting means 5 is provided with an upright flange 7 adapted for engagement with the outer face of the web of the rail, and provided with apertures for bolts 8 by vmeans of which it may be attachedl to-the rail.' Said'- supporting finem- Patentefd nee. 2, 1919.

The'

ber is also provided with a base flange 9 for engagement with the top faceof the rail base iange, and with longitudinally spaced lugs 10. These lugs 10 carryva non-rotative shaft 11 extending parallel to the rail A and constituting the member upon which the rockarin 4, connected to the derailing block 3, is hinged. Each of the :lugs 10 has a vertical, elongated slot 12, of a width substantially equal to the diameter of the shaft 11, the vertical sides of said slot being pro` vided with vertically spaced notches or keyways 13, adapted to receive oppositely placed keys 14, 14, fixed to the .shaft 11. There are two pairs of such keys fixed to the shaft. Manifestly, the shaft may be adv f -'opposite the rail A operates to swing the arm l4 so as to apply or remove the derailing block 3 Vto orfrom the rail, as desired, inv

the usual manner. f

' Upon the Vrock arm 4 and projecting downwardly below the level of the shaft 11, is an arresting arm 17 suitablyV apertured to carry a screw threaded bolt 18. The exact angle at which this arm 17 willproject with respect to the plane of general direction Vof '-thearm 4 will vary according to the style or type of Vderailing device to which it is ap` plied, and the location of the non-rotative shaft 11 with respect to the rail base; the object being to so shape the arm 17 that its contact facel 19 will, when -the arm 4 is swung away from the rail A, lie beneath and substantially parallel to theV bottom of the supporting base 20 of the rail A, and so that the end 21 of the adjusting bolt 18 will contact with said rail base 20. By moving the bolt V18 in and out, variations in the adjustment of the shaft 11 to accommodate rails of different heights, will be compenf sated for.

" Vhere the derailing device is not adjustable, the shape of the `projecting arm 17 may:

be such thaty the surface-19 thereof may contact. with-the base 2O of the rail; but it isl moreA desirable even in such instances, to

Y f use the adjusting bolt 18 to cover variations in the vmanufacture'of parts, as well as the wear. j

seen that lthe rail base 20 on the moving or rocking arm 4, and toV arrest the movement of the latter when directed away from the rail A; and it will V the boltsl 23.

also be seen that adjustable means is provided by the bolt 18, whereby the throw of the arm 4 may be regulated to suit the various conditions that may be encountered in practice. Y

VWhile I Vhave shown, in F ig. 2, that theV arm 17 is cast integral'with the rock arm 4, it will be apparent that such arm may be applied to existing devices. Thus I have shown the modification in. Fig. 3 whereby the arm 17 is `provided with an extension 22 having suitable apertures to, receive bolts '23 whereby the arm 17 may bebolted to the rock arm 4. By.V this means my improvement may be applied to derailing devices'f Vof a derailing block, means for'operatively supporting-said derailing block` for motion to and from derailing position, andmeans movable with theY derailing block, adapted to arrestit by contact with the rail base.

In a derailing` device, the combination of a derailing block, an arm fixed thereto, means for operatively attaching said arm in a position adjacent to a rail, means for vertically adjusting the aXis of .rotation of said arm to accommodaterails ofdiiferent heights and means for arresting the rotativeV movement of theV arm.

4. In a derailing device, the' combination ofa derailing block, an arm fixed thereto, means'` for operatively attaching said arm in a position ,adjacent to a rail, means for vertically adjusting'the axis of rotation of said arm to accommodate rails of dilferent heights land adjustablemeans for arresting the rotative-movement of the arm.

5. In a derailing device, the combination of a derailing block,Y a rock arm xed theregto, a supporting member Aadapted to be attached to the rail, means whereby the rock arm is rotatively connected tosaid supporting member "and means on the roclr arm j adapted for cooperation with the rail'base to arrest therotative movement of the'rock arm.

In a derailing device, the" combination of a derailing block, a'rockarmfxedthereto, a supporting memberadapted to be attachedto lthe rail, means whereby therocl arm is rotatively connected to said supporting member and means on the rock arm adapted for coperation with the rail base to arrest the rotative movement of the rock arm, said means comprising a lug or arm projecting in a direction away from the de- -V railing head.

7 In a derailing device, the combination of a dera-iling block, a rock arm fixed thereto, a supporting member adapted to be attached to the rail, means wherebyT said rook arm is rotatively connected to said supporting member, means for vertically adjusting the axis of rotation ofsaid arm to accommodate rails of diierent heights, a lug on said rock arm projecting belovv the level of the axis of rotation, a bolt adjustably mounted on said lug and adapted in copn eration with the rail base, to limit the rotative movement of the rock arm.

In testimony, that I claim the foregoing as my invention I affix my Signature in the presence of two Witnesses, this 9th day of November A. D., 1918.
